Trying to figure out the problem...

[Sorce]

Okay, so I recently built a system:

Motherboard: Gigabyte GA-P35-D3SP ver2.0
CPU: Intel C2D E7200 w/ Tuniq Tower 120 Cooler
RAM: G.Skill 2x2GB DDR2 800
Video: ATi Radeon x300
Case: Thermaltake Tsunami
Power Supply: 610W PC Power and Cooling
Hard Drive: 250GB Seagate Barracuda

I get everything connected, and power it on. The LEDs glow, the fans spin, but nothing else. No signal to the monitor, no beeps. The first time I figured I did something wrong, but I checked all the connections and they seemed tight, powered the system back up and got the same result. Then I thought my processor may not be compatible with the BIOS, so I found a Celeron from the earliest known compatible BIOS for my motherboard, still with the same result.

Other solutions I've tried:
-Disconnecting everything and starting with just the CPU plugged in.
-Switching around and Re-seating the RAM
-Switching around the Video card
-Resetting the CMOS (jumper switch)
-Pulling the BIOS battery

Things I noticed that might help:
-The CPU fan doesn't spin up at all while everything else does.
-The motherboard didn't come with any of those plastic washers that separate the screws from the board itself. I don't know if this is an issue nowadays or not, since I haven't built a computer in 5 or so years.

So... does anyone have any ideas as to what the problem is/could be?

could be that the RAM is no good, try the sticks out on another system and see if it works.

I pulled the RAM from the machine and tried to boot it, and there was no beep code, so I don't think that's the problem. Regardless, I don't have another machine on hand to test it. But thanks for the suggestion.

With no RAM you should get a POST code complaining about it. That points to a bad CPU or mainboard, but you might try a different cpu fan first just for fun.

I have two different processors (and power supplies) on hand, and neither of those worked, so I'm going to RMA the motherboard and hope that fixes the problem.
